Reese Witherspoon and Ryan Phillippe

By Rebecca Winters Keegan

They pose so graciously together on the red carpet that it came as something of a surprise when this cinematic couple stopped clicking. In mid-October, at the premiere of Phillippe's Flags of Our Fathers, the fair-haired pair, married since 1999 and parents to Eva, 7, and Deacon, 3, bickered. Rumors swirled that Phillippe had been having an affair with a co-star. By November, Witherspoon, who once talked openly about attending couples counseling, filed for divorce. The Walk the Line star went off to work on her next film, Rendition, with Jake Gyllenhaal, while Phillippe issued a statement saying, "I'm not a perfect person." Which, frankly, really bums us out.
